Kemble Primary Levelled approach to calculation in Division (inc. related mult levels) FS and L1 Relate multiplication and division to practical experiences Practical / recorded using ICT (eg digital photos / pictures on IWB) Pictures / Objects Rapid recall and mental calculation 6 cakes shared between 2 Halves of even numbers up to 20 6 cakes shared between 2 6 cakes put into groups of 2 6 cakes put into groups of 2 L2 L3 2c. Learn 2x and 5x table Recognise key words associated with multiplication Continue to use multiplication and division in practical situation 2b. Quickly recall 2x 5x 10x tables and know related division facts Start to learn 3x 4x tables Recognise that multiplication is repeated addition Begin to understand division as grouping Understand that halving is the inverse of doubling 2a.Learn and recall 3x 4x tables and related division facts Multiply TU by U (up to 5 ) Begin to know the key words associated with multiplication and use them in problem solving Know that to find a quarter of a number it must be divided or shared by 4 and demonstrate on a number line Practical / recorded using ICT 3c. Learn 4x 6x tables and associated division facts Cement understanding that division is sharing and like repeated subtraction and be able to show this on a number line. Divide TU by U Recognise the key words associated with multiplication and division when solving problems Use mental calculation skills and approximate 3b. Learn and recall 4x 6x 7x8x9x tables and division facts Work out appropriate methods to help with division and know that they often have remainders Estimate the answer to check Know the key words associated with multiplication and division 3a. Demonstrate secure knowledge of all x tables and apply them Recognise the relationship between multiplication and division and how it can be used Divide TU by U then HTU by U Check answers Begin to understand what happens when we multiply by 10 and 100 Pictures / Symbols 15 5 0 Four eggs fit in a box. How many boxes would you need to pack 20 eggs? Also: 25 ÷ 5 = 5 Number lines (start from zero) 96 6 = 16 10 x 6 Know and use mult and div facts for 2,5,10 Number lines / Arrays How many apples in each bowl if I share 12 apples between 3 bowls? 5 10 Leading to… Partitioning 28 2 20 2 = 10 82= 4 76 ÷ 6 = 12r4 10 X 6 = 60 2 X 6 = 12 72 Halves and doubles of even numbers up to 20 and beyond. (with 2x,5x,10x) Partitioning with multiples of the divisor 6x6 15 All tables and division facts by 3b. (start with 2,3,4,5,6,10) Halves and doubles to 100 Multiply simple whole numbers by 10/100 L4 L5 4c. Understand what happens when we multiply and divide by 10 and 100 and apply a quick method Know all x tables and division facts Begin to develop an efficient method for HTU divided by TU Approximate answers first and use X and division skills in problem solving 4b. Continue to develop and refine long multiplication and division skills Use approximation to check answers Solve problems using a calculator Multiply and divide decimals by 10 and 100 and whole numbers by 10,100, 1000 Use multiplication and division to solve multi- step problems 4a. Carry out HTU x TU and HTU divided by TU with consistent accuracy Multiply and divide to 1 decimal place Use the inverse to check answers Use multiplication and division skills to solve word problems in real life Use a calculator to solve problems Multiply and divide whole numbers and decimals quickly by 10,100 and 1000 ‘Short’ division 5c. Carry out long division and multiplication with consistent accuracy Multiply a decimal number with up to 2 decimal places by a single digit Divide a number with up to 2 decimal places by a single digit Use multiplication and division to solve multi step word problems involving money including conversions to and from foreign currency and % Use calculator to solve problems 5b. Multiply a decimal number with up to 2 decimal places by 2 digit numbers Refine written methods of long multiplication and division to ensure efficiency while maintaining accuracy Use multiplication and division to solve problems in a variety of contexts using written methods and a calculator Judge whether an answer is reasonable and check results As Level 4 Multiply and divide whole numbers and numbers with 1 decimal place by 10/100/ 1000 Expanded short division 291 3 (estimate: 270 3 = 90) 1 9 r2 12 When divisor is a single digit 2 11 230 This uses a jotting style to support but still needs children to access multiples of 2 digit numbers quite quickly. 12 24 36 48 60 72 84 96 108 It is likely that most children working at level 5 will have efficient formal methods for single digit and an efficient informal method for two digit divisors. Relate tables and division facts such as 0.2 x 30 = … Halves and doubles of all numbers up to 100 including simple decimal numbers. Apply division to other areas of maths such as fractions Use division naturally in a range of situation i.e. tables, division facts and associated facts, FDP, factors etc
